CHAPTER ONE
1.1. Introduction
Nigeria's economic recovery programmes have necessitated a radical shift from total dependence on government for job to self-employment. One such attractive area for self-employment is snail rearing. It is a great money-spinning business that can provide a substantial source of protein to complement Nigerian carbohydrate meals. Sadly Nigerians inclination to go into business in the fields where thousands have already made their fortune has led to the ulter neglect of such lucrative area of snail farming in Nigeria or export at international market. Many people see snails here and there. Some people take it as meat. But quite a number don't know how to go about rearing them. This is made worse because snails, which belong to the family of animal called MOLLUSCA, is a hermaphrodite. It has both the female and male sexual organs; so one cannot really distinguish between the male and female specie of it. 1.2. Overview

Snails that respire using a lung belong to the group Pulmonata, while those with gills form a polyphyletic group; in other words, snails with gills form a number of taxonomic groups that are not necessarily more closely related to each other than they are related to some other groups. Both snails that have lungs and snails that have gills have diversified so widely over geological time that a few species with gills can be found on land and numerous species with lungs can be found in freshwater. Even a few marine species have lungs. Snails can be found in a very wide range of environments, including ditches, deserts, and the abyssal depths of the sea. Although many people are familiar with terrestrial snails, they are in the minority. Marine snails constitute the majority of snail species, and have much greater diversity and a greater biomass. Numerous kinds of snail can also be found in fresh water. Most snails have thousands of microscopic tooth-like structures located on a ribbon-like tongue called a radula. The radula works like a file, ripping food into small pieces. Many snails are herbivorous, eating plants or rasping algae from surfaces with their radulae, though a few land species and many marine species are omnivores or predatory carnivores.

CHAPTER THREE
3.1. Problems of snail production
1. Population Control
This is a sticky subject for a lot of people but it's important to think about this sensibly if you intend to keep snails. With certain species able to lay 1200+ eggs in one year it is completely impractical to hatch all your eggs. And with most species, eggs are almost guaranteed. So let's deal with the options you have or may have heard: 1. Keeping snails isolated

This is a common suggestion but I don't think it is a practical solution for a number of reasons. I'd favour the opinion that snails do best with others and most people wouldn't wish to keep one snail, and you may not have the tanks to start splitting them all up. Also, some species of snail can self-fertilise if necessary. 2. Picking snails that are notoriously hard to breed or in high demand This isn't a bad suggestion; you'll not have any trouble finding homes for the babies. Remember though, that new breeds are in high demand but may not necessarily be difficult to breed. Your first few clutches may fly out the door, but it's likely those new owners will have similar success. Some...
